ou are interested in testing the effectiveness of a new program designed to teach reading skills to elementary school students, describe how you would use a experimental design design to test the effectiveness of the program. Which type experimental design would you deploy? What type of conclusion can be drawn from the experiment?

Expert Solution

Null Hypothsis: The new program will not be effective for the elementary school students.

Alternative Hypothsis: The new program will be effective for the elementary school students.

Samle: Elementary School Students

Sample Size: Total 80 Students. 40 in each group.

Tools: i. The new Program for Teaching Reading skills to students ii. Questionaire or scales to measure reading skills

Independent Variable: The new Program for Teaching Reading skills to students

Dependent Variable: Reading Skills

Design: Between Groups Experimental Design

Method: Two groups of 40 students each will be made, total of 80 in both the groups. Random assignment of students should be done to assign them in group 1 or group 2, they should have equal chance of falling in either group. They should be matched on age, sex and other other variables. It should be made sure that extraneous variable are controlled.

Group 1 will the experimental group, in which the new program to teach reading skills be be administerd on the students.

Group 2 is the controll group, no instruction of any reading program will be given.

This will be followed for a specified number of days for both groups. After the program, the scale used to measure the reading skills should be administed on both the groups.

Results: Scoring is done on the reading tests of both groups, and analysis may be done using Independent Sample T-test.

A researcher interested in the treatment of depression developed an intensive treatment program designed to teach people to think positively. The researcher began the study by recruiting 50 college students who received extremely low scores on a well-validated measure of self-esteem. Each of the 50 participants agreed to attend four 1-hour therapy sessions per week for two weeks (for a total of eight sessions). Thirty-seven of the 50 original participants remained in the study and completed all eight sessions. At...

Question 1 Researchers are interested in testing the effectiveness of a new immunosuppressive therapy to be used post-transplant to reduce graft failure in the host. Suppose researchers investigating this new therapy are concerned about the dangerous side-effects of the drug. For instance, participants that would like to enroll in the study are not allowed to already have diabetes, as the immunosuppressive agent has been found to drastically increase fasting glucose levels, which could be very dangerous for diabetics. This means,...

Researchers are testing the effectiveness of a new smoking cessation program. At the close of the program the mean number of cigarettes smoked for the 328 people who completed the program was 4.3 with a standard deviation of 5.22. The mean number of cigarettes smoked per day for the 298 people who did not complete the program was 13 with a standard deviation of 8.97. Is there a difference between the two means? Use a 5% level of significance to...

Researchers are interested in testing the effectiveness of their new therapy technique (Explosive Therapy) by comparing it to a standard therapy technique (Cognitive Redecorating), a controversial newer treatment (Ludovico) and a no-treatment (wait list) control. Twelve clients are randomly assigned to the three groups. Blind raters evaluate the “mental health” using a validated instrument yielding scores from 0 to 10, where 0 indicates very poor mental health and 10 represents very good mental health. Perform an ANOVA on these data....

Question 2 Suppose a researcher is interested in the effectiveness in a new childhood exercise program implemented in a SRS of schools across a particular county. In order to test the hypothesis that the new program decreases BMI (Kg/m2), the researcher takes a SRS of children from schools where the program is employed and a SRS from schools that do not employ the program and compares the results. Assume the following table represents the SRSs of students and their BMIs....

A learning researcher is interested in the effectiveness of her new memory enhancement program. To test this program, she has 15 students learn a list of 50 words. Memory performance is measured using a recall test. After the first test, these same students are instructed as to how to use the memory improvement program and then learn a second list of 50 different words. Memory performance is again measured with the recall test. If you wanted to test the hypothesis...

A researcher is interested in comparing the effectiveness of two reading programs to see if there is a difference in the average amount of student reading score improvements reported in either program. The following data is collected from students in each program after four months of participation. Using the below data, conduct the appropriate two-sided hypothesis test to answer the researchers' question. Experimental Comparison 35 2 40 27 12 38 15 31 21 1 14 19 46 1 10 34...
